CM14 Installation

3 Installation

3.1 Incoming acceptance, transport, storage

The permitted ambient and storage conditions must be observed. The precise specifications can be found in Section "Technical data" →  37.

3.1.1 Incoming acceptance

On receipt of the goods, check the following points:
• Are the packaging or contents damaged?
• Is anything missing from the delivery? Compare the scope of delivery with the information
you specified in the order.

3.1.2 Transportation and storage

Note the following points:
• Pack the device so that is protected against impact for storage and transportation. The
original packaging provides optimum protection.
• The permitted storage temperature range is –40 to +85 °C (–40 to +185 °F); it is possible to
store the device in the borderline temperature ranges for a limited period (maximum 48 hours).

3.2 Installation

NOTICE
Overheating due to heat accumulation in the device
To avoid heat accumulation, please always make sure the device is sufficiently cooled.
If the device is operated in the upper temperature limit range, this reduces the operating
life of the display. The transmitter is designed to be used in a panel. The orientation is determined by the readability of the display. Connections and outputs are
fitted on the rear of the device. The wires are connected by means of number-coded terminals. Ambient temperature range:–10 to +60 °C (14 to 140 °F)

3.3 Dimensions

Observe the installation depth of 150 mm (5.91 ") for the device incl. terminals and fastening clips.
More dimensions can be found in Section "Technical data" →  37.
• Panel cutout: 92 mm x 45 mm (3.62 in x 1.77 in).
• Panel thickness: max. 26 mm (1 in).
• Max. viewing angle range: 45° to the left and right from the central display axis.
• If the devices are arranged horizontally beside one another in the X-direction, or arranged
vertically on top of one another in the Y-direction, the mechanical distance (specified by the housing and front section) must be observed.

Installation CM14

3.4 Installation procedure

The required panel cutout is 92 mm x 45 mm (3.62 in x 1.77 in).
A0015216
 2 Installation in the panel
1. Screw the threaded rods (item 2) into the positions provided on the mounting frame (item 1). Four opposing screw positions (item 3/4) are available for this purpose.
2. Push the device with the sealing ring through the panel cutout from the front.
3. To secure the tube in the panel, hold the device in a horizontal position and push the installation frame (item 1), with the threaded rods screwed in, over the tube until the frame locks into position.
4. Tighten the threaded rods to fasten the device in place.
To disassemble the device, the mounting frame can be unlocked at the locking elements (item
5) and then removed.

3.5 Post-installation check

• Is the sealing ring undamaged?
• Is the mounting frame securely engaged on the housing of the device?
• Are the threaded rods tightened?
• Is the device positioned in the center of the panel cutout?

WARNING
L
Danger from electrical voltage
The entire connection of the electrical system must take place while the device is de-
energized.
Danger if protective ground is interrupted
The protective ground connection must be established before any other connection is
made.
NOTICE
Thermal load of the lines
Use suitable lines for temperatures of 5 °C (9 °F) above ambient temperature.
Malfunction or destruction of the device due to incorrect supply voltage
Prior to commissioning, make sure the supply voltage matches the specifications on the
nameplate (bottom side of the housing).
Ensure the emergency shutoff of the device
Provide a suitable switch or power-circuit breaker in the building installation. This switch
must be provided within easy reach of the device and be labeled as a disconnector.
Protect device from overload
Provide a overload protection unit (rated current = 10 A) for the power supply line.
Incorrect wiring can cause destruction of the device
Observe the terminal designation on the rear of the device.
Energy-rich transients in long signal lines
Connect suitable upstream overvoltage protection in series.
It is permitted to connect a mixture of safety extra low voltage and voltage which poses a shock hazard to the relays.
